2 Corinthians 4:4-6

among them the god of this world [Satan] has blinded the minds of the unbelieving to prevent them from seeing the illuminating light of the gospel of the glory of Christ, who is the image of God. For we do not preach ourselves, but Jesus Christ as Lord, and ourselves [merely] as your bond-servants for Jesus’ sake. For God, who said, “Let light shine out of darkness,” is the One who has shone in our hearts to give us the Light of the knowledge of the glory and majesty of God [clearly revealed] in the face of Christ. [Gen 1:3]
